Spawn egg texture bugged when activating texture pack

For some reason, there is a random black spot in some of the spawn egg textures, this only happens when I activate a certain texture pack. If you look in the screenshots, some of the textures are glitched, not all. (like the allay spawn egg or axolotl spawn egg). I tried it with another texture pack but nothing happened. I also checked the texture pack files and everything seems to be normal
